| HVAC Estimated Demand |
The portion of the total HVAC load, adjusted for demand factor, connected to this panel. For example, assume that HVAC demand factors are specified as 100% for 0 VA - 100 VA and 50% for greater than 100 VA. Further, assume a total HVAC load for the project of 600 VA. When the HVAC demand factor is applied, the total estimated demand is (100 VA x 100%) + (500 VA x 50%) = 350 VA. Now consider three panels, P1 with a total HVAC load of 100VA, P2 with a total HVAC load of 200VA, and P3 with a total HVAC load of 300VA. Each panel’s portion of the total estimated demand (350 VA) is calculated based on their share of the total HVAC load connected. Thus, P1 = 1/6, P2 = 1/3, and P3 = 1/2 or 58.3 VA, 116.7 VA, and 175 VA, respectively. See About Demand Factors under Electrical Settings. |
